Improvement in tobacco-pipes

HENRY C. FINLAYSON, OF NEW YORK, N. Y.

IMPROVEMENT IN TOBACCO-FINES.

Specicaton forming part of Letters Patent No. 120,053, dated October 17,1871.

To all whom it may concern:

Be it known that I, HENRY C. FrNLAYsoN, of New York, in the county andState of New York, have invented a new and useful Improvement inTobacco-Pipes; and I d o hereby declare the following to be a full,clear, and eX- act description of the same, reference being had to. theaccompanying drawing forming part of this specification, in which thefigure is a longitudinal section of a pipe, showing my improvement.

My invention relates to that class of tobaccopipes which contains withinthe stem a metallic tube to collect the moisture and prevent its beingabsorbed by the bowl and stem, which tube is also adapted for removal,that it may be cleaned.

Various means have also been employed in connection with the metallictube to collect the saliva and moisture proceeding from condensation. Insome cases the stem itself has been formed in two parts connectedtogether by la screw-joint, and at or near the` joint one or the otherof the parts hollowed out to form a reservoir at the end of the tube.This construction, however, is objectionable, because the moisturecollected in the reservoir is absorbed, to a great extent, by the woodof the stem, making the latter strong and exceedingly unpleasant to thesmoker.

A metallic bulb has also been employed for this purpose, interposedbetween the two parts of the stem, receiving upon one side the metallictube and formed upon the opposite side with a screw-shank, to receivethe part of the pipestem carrying the mouth-piece. This construction ofa reservoir, while it collects the moisture, does not admit of beingcleansed, and, besides, destroys the symmetry of the stem. It alsodivides the stem into two parts, which have no connection with eachother beyond that afforded by the bulb and the metallic tube, so thatwhen the pipe becomes worn by frequent removal of the tube forcleansing, the bowl and lower part of the stem cannot be held in place,but slip olf the ytube and thereby destroy the whole plpe.

To overcome these objections, my invention consists in combining, withthe stem first above described and with the tube, a short metalliccylinder surrounding concentrically the end of the tube within thewooden reservoir, being supported upon a metallic d isk at the end ofthe tube, and held in place by the joint of the stem.

By this construction an annular chamber is formed in the reservoiraround the tube in which the moisture is collected and prevented fromcoming in contact with the stem to render it offensive.` By unscrewingthe two parts of the stem the cylinder and tube are readily removed fromthe pipe for cleansing.

By this construction I uniteall the qualities said to be contained in awooden stem with the advantages derived from a metallic reservoir,without in the least enlarging the stem or destroying its symmetry.

In the drawing, A is the bowl of the pipe and B is a hollow shank ofwood, on the end of which is cut a screw-thread to allow the end of thewooden joint-coupling C to be screwed onto it. Into the bore ofthe shankB I insert an open tube, D, which extends through as far as thepipe-bowl, in which position it is held by the disk or iian ge E,whichsurroun dsV the tube and bears against the end of shank B. The front endof the tube extends a little distance forward of the flange E and issurrounded by an outer concentric tube or cylinder, F. This cylinderprojects from the face of the flange E a short distance beyond the endof said tube D, thereby forming an annular chamber, Gr, around the tube,the bottom of which is closed by the flange, its upper end being leftopen. The inside of the joint-coupling (l is made large enough indiameter to receive the cylinder F, and is provided with an interiorshoulder, H, which, when the coupling is secured onto the shank B, bearsagainst the iiange E and the cylinder, thereby holding the latter inplace and preventing the longitudinal movement of the tube D. The frontend of the joint-couplingis provided with a mouthpiece, I, in the usualmanner.

Having thus described my invention, what I claim as, new therein, anddesire to secure by Letters Patent, is-

In combination with the wooden shank B of the pipe, the woodenjoint-coupling C and the removable metallic tube, D, the short metalcylinder F and metallic iiange E, arranged within the stem, as hereinset forth and shown, for the purpose specified.
